Now that you have a basic understanding of the tools and expertise required let’s delve into the costs associated with skylight installation.

Understanding the Costs of Skylight Installation

Additionally, you will need to purchase the proper flashing or a flashing kit, which can range from $100 to $400. Other costs to consider include various tools, shingles, and additional materials.

Step-by-Step Guide to Skylight Installation

Whether you hire a professional roofing company or tackle the installation yourself, it’s essential to understand the step-by-step process of installing a skylight. While DIY installations can be time-consuming, they can also be rewarding. Let’s break down the steps of installing a skylight on your roof.

Step 1: Cut the Roof Opening

The first step is to cut the roof’s opening for the skylight carefully. Begin by selecting a day with good weather to avoid any complications. Determine the location and size of the skylight from inside your home. Ensure that the skylight is positioned between joists for proper support. Suppose you plan to install a large skylight requiring the cutting of multiple roof rafters. In that case, it is advisable to seek professional assistance to avoid compromising the structural integrity of your roof.

Once you have marked the dimensions, use deck screws to indicate the corners on the exterior roof. Remove the shingles within the marked area and use a circular saw to cut out a rectangle following the chalk lines.

Step 2: Install the Flashing

Next, install the flashing along the entire window sill. The flashing acts as a barrier to prevent leaks. Apply self-adhesive flashing on each side and fold it over the edge to create a barrier the width of the skylight sill. Secure the flashing by nailing it down using a roofing nailer.

Step 3: Place the Skylight

With the sill flashing in place, carefully position the skylight in the cut-out area with the assistance of a friend or a pulley system. The skylight should have a flange edge where you can secure it using 1.25-inch roofing nails.

Step 4: Seal the Edges

To ensure a watertight seal, cut a self-adhesive membrane to stick to the skylight’s flange, extending a few inches past its edge. Apply the membrane on all sides of the skylight to create a barrier against leaks.

Step 5: Install Sill Flashing

Your skylight should have a U-shaped piece of flashing to place on the bottom sill. Slide the sill flashing into place and secure it on all sides using a roofing nailer. Reinstall the shingles over the flashing, covering the bottom of the skylight window.

Step 6: Install Step Flashing

Install step flashing on each side of the skylight, starting from the bottom and working your way up. Secure the first l-shaped step flashing piece near the bottom and cover it with a shingle. Continue installing step flashing pieces, overlapping the previous ones by a few inches, and securing them with shingles. Repeat this process on both sides until you reach the top corners.

Step 7: Install Counterflashing

Click the counterflashing into place over the step, flashing on each side. This step is crucial for preventing snow and rain from entering under the edge of the skylight.

Step 8: Install Saddle Flashing

Slide the saddle flashing under the shingles above the skylight and secure it with roofing nails. Reinstall the shingles over the saddle flashing to ensure a watertight seal.

Step 9: Enjoy Your Skylight!

With all the flashing, shingles, and skylight in place, it’s time to admire the fruits of your labor. Safely descend from the roof and head inside to check that everything looks good from the interior. If your skylight is designed to open, test it to ensure smooth operation. Take a moment to bask in the natural light filling your home.

Conclusion

Installing a skylight can be a rewarding project that brings more natural light into your home. Following this comprehensive step-by-step guide, you can install a skylight on your roof. Remember to prioritize safety; if you are unsure about any step of the process, it’s always best to consult a professional. Enjoy the benefits of a well-lit and refreshing living space with your new skylight installation.
